It wasn't Peter Drucker who said "Measure What You Manage."It was the scientist Lord Kelvin who originally stated " When you can measure what you are speaking about and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts the advanced stages of science".

This became abbreviated, revised and attributed to many management gurus. Success Can Be Measured Daily. Pick a personal data point - Dollars, Calls, Contacts, Hits, Followers, or whatever and establish your daily average performance. Then strive to exceed it.
